CONNECTION TO A GENERATOR
The machine can work with generators as long as the auxiliary power matches these requirements :
- The voltage must be AC, always set as specified, and the peak voltage below 400V,
- The frequency must be between 50 and 60 Hz.
It is imperative to check these requirements as several generators generate high voltage peaks that can damage these machines.
USE WITH EXTENSION CABLES
All extension cables must have an adequate size and section, relative to the machine's voltage . Use an extension that complies with national safety
regulations. The power cables, extensions and welding cables must be fully uncoiled to prevent overheating.
